Teenager to face court for striking police

An Australian Federal Police protection officer suffered a gaping head wound when he was bashed by a 17-year-old youth during Sydney's Muslim riots, police say.

The teenager was arrested late on Tuesday night in Padstow, in Sydney's southwest, after police identified him on video footage of the violence.

Detectives seized several items of clothing from the property where the teenager was arrested, including jumpers or T-shirts believed to carry the "sixth pillar" slogan that some of Saturday's rioters were wearing.

The slogan is thought to be a reference to jihad or Muslim "struggle".

At a media conference on Wednesday, Superintendent Mark Walton would not reveal whether or not the teenager was already known to police.

He has been charged with hitting the AFP officer with a pole outside the US consulate in Martin Place.

The youth has also been charged with attacking a NSW police officer during Saturday's anti-West demonstrations and will appear in court next month.

The AFP officer is recovering from his head injuries at home while the NSW officer suffered no serious wounds.

It's the eighth arrest from Saturday's violence and more are expected as officers trawl through footage and images of the riots.

"It's quite an extensive task to pull all that material together, identify anyone who's been involved in offences and ... commence the phase of arresting them," he told reporters.

Supt Walton refused to say if police would be at a meeting in Auburn in Sydney's west on Wednesday night where controversial Sheik Feiz Mohammed is expected to preach about the Innocence of Muslims video which sparked Saturday's riots.

The US-made short film, on YouTube, mocks Islam and has angered Muslims around the world.

Sydney's branch of the Ahlus Sunnah Wal Jama'ah (ASWJ) movement has planned the Auburn meeting as a lecture on "the Honour of the Prophet" and to discuss "what our responsibilities are regarding this matter".

Sheik Mohammed was widely condemned in 2007 for his DVDs calling for the murder of "infidels" and describing Jews as "pigs".

He has reportedly also previously said in a speech that raped women only have themselves to blame.

Responding to reports of a possible anti-Muslim demonstration in Sydney this weekend, Supt Walton said he had no specific information about police action to counter any gathering.

"The police are working hard to ensure that this city remains as safe as it possibly can," he added.

"And it's pretty much business as usual - that's our expectation.

"That said, we're in a position to respond should anything escalate as it did at the weekend."
